Overcoming movement obstacles by the religiously orthodox: the Muslim Brotherhood in Egypt, Shas in Israel, Comunione e Liberazione in Italy, and the Salvation Army in the United States.

This article examines four movements of the religiously orthodox that should have failed according to most social movement theory and research. The movements combine (1) an extraordinarily broad agenda, (2) a strict, morally absolutist ideology, and (3) a strong proscription against compromise with other groups, each of which has been identified as a liability that can lead to movement failure. Through inductive, qualitative analyses, the authors identify four shared strategies that helped these movements overcome these obstacles: bypassing the state, building grassroots structures, providing graduated membership, and reprioritizing agendas. Analyses of these movements also suggest that particular combinations of movement “liabilities” may actually be advantageous.
